    When a “pernet A” was pulled up, a “cow-sucker” was inserted and dropped into the reticulum, and then a kicking-up process was carried out. A piece of metal with a lustrous pointed end, which was presumed to have been stuck into the gastric wall, was recovered from two cases out of thirty from which a pernet A had been pulled up.
    Before the kicking-up process came into practice, a pernet A had frequently been adsorbed at the pointed end of the cow-sucker and taken out at the time of pulling out. Because of the kicking process, a pernet A, together with many pieces of metal, was attached closely to the magnet of the cow-sucker in a parallel way and pulled out. Many of these cows involved manifested no clinical symptoms of any traumatic disease at the time of use of the permanent magnetic bar.
    If such matallic foreign body as this is left in the bovine body without being removed, there will he a danger for the cow concerned to attract some type of disease in future. In an experimental area, the frequency of occurrence of digestive diseases decreased remarkably after the administration of pernet. Taking these results into consideration, it seems to be most important for the prevention of traumatic diseases to apply pernet A and pull it up in the cow.

    1. A survey was conducted on 77 Landrace pigs which were introduced into Haibara County, Shizuoka Prefecture, from overseas in January and February, 1963. As a result, it was found that '30 pigs (39per cent) had stillborn young or given birth to piglets which died immediately after birth, presumably due to Japanese B encephalitis, in the summer and fall of 1963.
    2. Another survey was carried out on 148 breeding sows which had been mated in Ogasa, Haibara, and Shida. Counties, Shizuoka Prefecture, during a period from March to July, 1963. The rate of successfully grown young among the sows born prior to July, 1962, was 85 per cent among those inoculated against Japanese B encephalitis and 64 per cent among those not inoculated. The same rate among the sows born in and after August, 1962, and Landrace sows imported in January and February, 1963, was 53 per cent among those inoculated and 25 per cent among those not inoculated. These results indicate that the inoculation against the disease was effective.
    3. Nineteen breeding sows which had suffered from fever during pregnancy showed abnormal parturition, without exception. In the case of fever occurring prior to 90 days of pregnancy, it was not infrequent that the whole fetuses of a litter suffered from still-birth or abortion. In the case of fever occurring after 91 days of pregnancy, some of the fetuses of a litter suffered from stillbirth and not a few piglets succumbed immediately after birth.

    On a poultry farm exposed to infection with avian respiratory mycoplasmosis, 160 69-day-old chicks were divided into five groups. Four groups were administered with chlortetracycline, oxytetracycline, a mixture of streptomycin and dihydrostreptomycin, and tylosin, respectively, so that evaluation might be carried out on the effect of each antibiotic for the prevention of avian respiratory mycoplasmosis. The remaining group served as an untreated control.
    1) Judging from clinical symptoms, increase in body weight, and results of isolation of nonpathogenic pleuropneumonia-like organisms from tracheal mucus, chlortetracycline and tylosin seemed to be effective for the prevention of mycoplasmosis.
    2) The number of birds giving a positive aglutination reaction to mycoplasmosis and that of birds affected with sinusitis were much smaller in any of the experimental groups administered with the drugs than in the control group.
    3) In the experimental groups, except one which had been administered with the mixture of streptomycin and dihydrostreptomycin, chicks positive for agglutination reaction to infectious coryza appeared during the experimental period.
    4) Isolation of Mycoplasma gallisepticum was negative in all the chicks, including those of the control group, at the time of autopsy. Accordingly, it was impossible to clarify any germicidal effects of the drugs in the body.
